Let s talk about !! Pray to the great gods!!

I've never seen such a powerful person, so you can put this problem in all the categories you know, but this classification seems to be extremely wrong.

You can't fight every day, and people will be annoyed if you fight every day.

I advise you to text first, so that two people have a time period to consider in the interval between receiving text messages. There was also an idea. You can see what else to say and what not to say.

Being able to avoid unnecessary detours at the beginning of a relationship is displacement in physics. Agree to get a glimpse of her character through text messages. I can take good control of her in the future.

It is recommended that you ask this question again in chemistry, and ask how two people can react. Hehe. It's worth a try!

It's awesome, it's physics

Love has risen to academics, Niu X

It's really hard to ask for this question, and it's related to physics!

Then you can figure out how to meet her as quickly as possible! （t=s/v)

6 (two) + 10 (two) = 1 (catty) in ancient times 1 catty = 16 taels So there is half a catty and eight taels and one saying.

Solution: Establish a plane Cartesian coordinate system and draw a scatter plot of (x,y), which shows that y has an obvious linear relationship with x.

1) Let y=ax+b. Set the conditions with the question, x=10, y=83, x 2=30, xy=210, the mean of x'= x 4 = 10 mean y of 4='=∑y/4=83/4=，∴a=[∑xy-(1/4)(∑x)∑y]/[x^2-(1/4)(∑x)^2]=，b=y'-ax'=。The functional relationship between y and x is y=.

2) Let x be the month, then on April 16, x=, water level y=.

3), from (2) when x is the month, then December 1 is exactly the end of November, that is, when x=11, **The water level on December 1 y=.

FYI.

A is wrong, although sulfuric acid can absorb water, but sulfuric acid is acidic, ammonia is alkaline, the two will react b wrong, sodium hydroxide can absorb sulfur dioxide because sulfur dioxide is acidic, sodium hydroxide is alkaline, and the two can be reflected.

a.Although concentrated sulfuric acid is absorbent, it cannot absorb water from the alkaline gas ammonia because the two react.

b.Sulfur dioxide tail gas is absorbed with sodium hydroxide solution, which is the acidity of sulfur dioxide, not oxidizing cThe electrolysis of magnesium chloride to produce magnesium is the oxidation of magnesium ions.

The answer is d

The image is in the fourth quadrant, so k is less than zero, and the area of the square is equal to 6, so k is equal to on that image, so 2 times m equals -6. Then m is equal to -3.
